EMA Product Lines We Repair
Our engineers are trained on the full EMA product range. Below are the major product families we service.
EMA AC Frequency Inverters
Three-phase variable frequency drives for motor speed control in pumps, fans, and compressors. Common failures include IGBT module breakdown, capacitor degradation, and encoder communication faults leading to loss of closed-loop control.
EMA Soft Starters (SFT)
Electronic soft-start devices reducing inrush current and mechanical shock during motor startup. Typical faults include thyristor faults, overheating, current imbalance detection, and control board failures in high-vibration environments.
EMA Servo Drive Systems
Precision motion control drives for robotic arms, conveyors, and indexing equipment requiring encoder feedback. Repair focus includes resolver interface faults, commutation errors, position drift, and resolver-to-digital converter (RDC) failures.
EMA DC Drive Controllers
Thyristor and transistor-based DC drive systems for metal processing, printing, and paper mills. Prone to armature ripple, commutator sparking detection faults, and field weakening circuit failures under load transients.
EMA Power Supply Modules (PSM)
24V and 48V regulated power supplies for control circuits and PLC I/O cards in distributed industrial systems. Common issues include transformer core saturation, voltage regulation faults, and overvoltage protection nuisance tripping.
EMA Communication Interface Modules
Modbus TCP, PROFIBUS, and CANopen interface cards for EMA drives integrating with Indian PLC systems. Failures stem from ESD damage on field terminals, firmware corruption, and clock synchronisation errors in multi-drop networks.

Common EMA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EMA equipment arriving at our workshop.
- ✓IGBT module short circuit in AC inverter — Thermal cycling from ambient temperature swings (40°C daily delta common in Indian warehouses) causes solder joint fatigue on IGBT power modules. Phase-to-phase short then develops over weeks, triggered by load surge or voltage transient.
- ✓Encoder communication loss (E1 / E2 fault codes) — EMA servo drives expect continuous feedback from resolver or incremental encoder. High-vibration textile machinery and cement kiln motors cause connector micro-fractures or encoder cable shield grounding failures, creating intermittent signal dropout.
- ✓Thermal overload relay nuisance trip — EMA soft starters and drives use electronic thermal model algorithms sensitive to ambient temperature and load duty cycle. Miscalibration during previous service or sensor drift causes false overload detection, shutting down production unexpectedly.
- ✓Capacitor degradation and DC bus voltage instability — Indian industrial sites often experience 10-15% mains voltage fluctuation and harmonic distortion from non-linear loads (welders, SCR drives). EMA electrolytic capacitors degrade rapidly in high-temperature, high-ripple environments, reducing filtering effectiveness.
- ✓Resolver stiction and mechanical friction errors — EMA resolver feedback systems in food processing and packaging lines accumulate dust and moisture in the resolver housing. Bearing grease oxidation and contamination cause rotor friction, generating jerky position signals and alignment errors.
- ✓Soft starter ramp slope control malfunction — EMA soft starters regulate current rise during motor start using ramp time setting (0.5-30 seconds). Control board potentiometer drift or firmware bug in older EMA SFT models causes erratic acceleration or failure to reach full voltage, leaving motor in current-limited state.

Frequently Asked Questions — EMA Repairs
Do you repair EMA equipment anywhere in India?+
Yes. Synchronics repairs the full EMA industrial electronics range — AC/DC drives, soft starters, servo controllers, power supplies, and communication modules. We provide PAN India door pickup service from Mumbai, Delhi, Bangalore, Hyderabad, Chennai, Pune, Ahmedabad, and all tier-2 cities. All repairs are completed at our Vadodara facility (Gujarat) with same-day urgent dispatch option.
What is the typical turnaround time for EMA drive repair?+
Standard EMA repair turnaround is 5-7 working days including diagnostics, component replacement, and comprehensive testing. For critical production-line failures, Synchronics offers 48-hour emergency service with expedited component procurement and accelerated testing. We maintain stock of common EMA IGBT modules, capacitors, and thyristor assemblies to minimise wait time.
Can you repair older EMA equipment from the 1990s-2000s?+
Yes, Synchronics specialises in legacy EMA equipment repair. We maintain technical documentation archives for discontinued EMA drive series and stock obsolete components including phase-control thyristors, transformer cores, and analogue control boards. For unavailable ICs, we perform component-level remanufacture or substitution with approved equivalents maintaining EMA performance specifications.
Do you offer on-site repair and commissioning at our factory?+
Synchronics provides on-site diagnostic and urgent repair service for critical EMA equipment at textile mills, cement plants, and steel facilities. Our field engineers carry portable oscilloscopes, curve tracers, and EMA commissioning tools. For full repair, equipment is transported to Vadodara for controlled testing environment. We handle soft starters and small drives on-site; larger inverters require factory workshop testing.
How do I know if my EMA drive has an internal fault or cable/motor problem?+
Synchronics performs systematic troubleshooting: we first isolate the drive from the motor and test with dummy load, then verify power supply quality and encoder signals (if servo system). Common misdiagnosis: fault codes E1/E2 blamed on drive when encoder cable is loose; overheating blamed on drive when motor is overloaded. Our engineers use EMA diagnostic software to read internal faults and voltage waveforms, identifying root cause accurately before quoting repair cost.
How do I send my EMA unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a EMA drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on EMA repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your EMA unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
